在这里，我有此代码，我正在尝试openingHoursView.ohLocation具有两个值“ value1”和“ value2”。openingHoursView.idNum的值“ id1”和“ id2”也是如此。
当我执行代码时，我只会得到一个名为“ value2”和“ id2”的按钮。所以我的问题是如何为openingHoursView.ohLocation和openingHoursView.idNum的值创建所有按钮
- (void)loadView {
storeAppDelegate = (StoreAppDelegate *)[[UIApplication sharedApplication] delegate];
int row = [storeAppDelegate.openingHoursLocationsDelegate count]-1;
for (int i = 0; i <= row; i++) {
openingHoursView = [storeAppDelegate.openingHoursLocationsDelegate objectAtIndex:i];
self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
self.view.backgroundColor = [UIColor whiteColor];
//create the button
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
//set the position of the button
if (i%2 != 0) {
button.frame = CGRectMake(30 , 100 , 150, 30);
}else {
button.frame = CGRectMake(30 , 100 + i*50, 150, 30);
}
//set the button's title
[button setTitle:openingHoursView.ohLocation forState:UIControlStateNormal];
//listen for clicks
[button addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
button.tag = [openingHoursView.idNum intValue];
//add the button to the view
[self.view addSubview:button];
}
}
-(IBAction) buttonPressed: (id) sender {
UIButton* button = (UIButton*)sender;
NSLog(@"User clicked %d", button.tag);
// Do something here with the variable 'sender'
}
对于openHoursView.ohLocation的解释objectAtIndex：0是“ value1”，对于objectAtIndex：1的解释是“ value2”。 openHoursView.idNum的相同过程
最佳答案
问题是您在做：
self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
self.view.backgroundColor = [UIColor whiteColor];
在
for循环中，因此每次迭代都会被覆盖。您只能在for循环之前执行一次。
